BACKGROUND
Accurate intra ocular pressure (IOP) measurement and monitoring using tonometry is a common clinical measurement in diagnosis and management of glaucoma, this is often a challenge in children. The ICare and Perkins tonometers are both handheld tonometers, Perkins uses applanation while ICare measures IOP with a rebound method.
OBJECTIVES
The objectives of research were to study the IOP values from each tonometer, compare the value of IOP readings from both tonometers, determined the ease of their use in young children and document the various positions in which the tonometers were used successfully in children.
METHOD
Intra ocular pressure readings were taken by two experienced examiners in upright position without sedation or anaesthesia. ICare tonometer was first used. Data were entered and analysed with SPSS 17 statistical package. The means were compared using paired sample T-test.
RESULTS
A total of 480 eyes of 240 persons, aged between 2months and 90years with a mean of 46.2±22 years had their intra-ocular pressure range between 3 and 44mmHg( Mean16.3±6) measured using ICare and Perkins tonometry. There was a high correlation, and no statistically significant differences in the mean IOP comparing ICare and Perkins tonometers. The mean difference in average IOP readings between ICare and Perkins was -0.08±2.8 (95% CI: 0.45-0.30; r=0.87, p= 0.68) for right eye and -0.15±2.8mmHg (95% CI -0.53 to 0.23; r=0.86, p=0.44) in the left eye The difference in the average IOP reading from both tonometers was within 2mmHg 288(66.2%) eyes. Among the 147 (33.8%) eyes with a difference in IOP greater than 2mmHg, Perkins was responsible for the higher IOP reading in 76(51.7%) and ICare in 71(48.3%) p=0.56. Among 42 eyes of 21 children aged ≤6years, IOP reading was successfully taken in 41(97.6%) and 21(50%) eyes with ICare and Perkins respectively without sedation or anaesthesia.
CONCLUSION
The IOP readings using the ICare tonometer compares well with that of Perkins tonometer. The ICare was easier to use in young children (≤6year olds) without sedation or anaesthesia in this African population.
背景
使用眼压计准确测量和监测眼内压（IOP）是青光眼诊断和管理中的一项常见临床测量，这在儿童中往往是一项挑战。ICare眼压计和帕金斯眼压计都是手持式眼压计，帕金斯眼压计采用压平式测量，而ICare眼压计采用回弹法测量眼压。
目的
本研究的目的是研究每种眼压计测得的眼压值，比较两种眼压计测得的眼压读数，确定其在幼儿中的使用便利性，并记录眼压计在儿童中成功使用的各种姿势。
方法
由两名经验丰富的检查人员在未使用镇静剂或麻醉剂的直立姿势下测量眼内压读数。首先使用ICare眼压计。数据录入并使用SPSS 17统计软件包进行分析。使用配对样本t检验比较平均值。
结果
共有240人480只眼，年龄在2个月至90岁之间，平均年龄46.2±22岁，使用ICare眼压计和帕金斯眼压计测量的眼内压范围在3至44mmHg之间（平均16.3±6）。两者相关性较高，比较ICare眼压计和帕金斯眼压计测得的平均眼压无统计学显著差异。ICare眼压计和帕金斯眼压计测得的平均眼压读数差异，右眼为-0.08±2.8（95%可信区间：0.45-0.30；r=0.87，p=0.68），左眼为-0.15±2.8mmHg（95%可信区间-0.53至0.23；r=0.86，p=0.44）。两种眼压计测得的平均眼压读数差异在2mmHg以内的有288只眼（66.2%）。在眼压差异大于2mmHg的147只眼（33.8%）中，帕金斯眼压计测得的眼压读数较高的有76只眼（51.7%），ICare眼压计测得的眼压读数较高的有71只眼（48.3%），p=0.56。在21名年龄≤6岁儿童的42只眼中，分别使用ICare眼压计和帕金斯眼压计在未使用镇静剂或麻醉剂的情况下成功测量眼压的眼数分别为41只眼（97.6%）和21只眼（50%）。
结论
使用ICare眼压计测得的眼压读数与帕金斯眼压计测得的结果比较良好。在这个非洲人群中，ICare眼压计在未使用镇静剂或麻醉剂的情况下，对于幼儿（≤6岁）更容易使用。
